This study assesses the association between socio-environmental factors and urban sanitation conditions with the prevalence of intestinal parasitosis in a community on the periphery of the city of Manaus. The study comprised a socio-environmental survey and a parasitological inquiry. A heterogeneous community was revealed with some socio-economic and environmental differences between the micro-areas evaluated, even though the urban sanitation conditions were found to be predominantly precarious. The prevalence of intestinal parasitosis was 44.2%. There was no significant difference between the micro-areas that could explain the occurrence of intestinal parasitosis. An association was found between intestinal parasitosis and residential building types, age bracket and the quality of the water used for personal hygiene and consumption in the home. Open air sewage was a risk factor associated with intestinal parasitosis (OR=6.72; p=0.034) and also with intestinal protozoa (OR=21.87; p=0.004). In terms of the presence of protozoa, two risk factors were verified: the dumping of sewage directly into the river system (OR=12.98; p=0.011) and the use of rudimentary cesspits (OR=9.54; p=0.019).
本研究评估了社会环境因素和城市卫生条件与玛瑙斯市周边一个社区肠道寄生虫病患病率之间的关联。该研究包括一项社会环境调查和一次寄生虫学调查。研究发现，尽管城市卫生条件大多不稳定，但在评估的各个小区之间存在一些社会经济和环境差异，呈现出一个异质性社区。肠道寄生虫病的患病率为44.2%。各小区之间没有显著差异可以解释肠道寄生虫病的发生情况。研究发现肠道寄生虫病与住宅建筑类型、年龄组以及家庭个人卫生和饮用用水质量之间存在关联。露天污水是与肠道寄生虫病相关的一个风险因素（比值比=6.72；p=0.034），也是与肠道原生动物相关的风险因素（比值比=21.87；p=0.004）。就原生动物的存在而言，验证了两个风险因素：污水直接排入河流系统（比值比=12.98；p=0.011）和使用简易化粪池（比值比=9.54；p=0.019）。
